I have tried removing/masking ink on discs I wanted to trade and have had no luck on removal. I can spend some time and make it lighter but it does not come off at least for me. I think your just stuck

Once you're ready dump it out and wash all the dye off, then peel the glue off.

My pop used to dye b&w photos and he'd mask with rubber cement, anyone'd tried it? Good / bad results? Or is elmer's just the right thing?
